ALS X PLL was relocked after PSL work
Disabled PLL auto locker, reset the temperature feedback ("Crystal Frequency (MHz)" in the ALS_CUST_PLL screen) to zero, enabled auto locker, and it just worked.
Right now the temperature feedback is small (about 17-18MHz).
H1:ALS-C_FIBR_EXTERNAL_DC_NORMALIZED is about 0.8, which is somewhat smaller than before (1.1-ish on Friday) but not much and it's still good.
